Abstract	The South African component of the international South Atlantic Meridional Overturning Circulation project (SAMOC-SA) aims to characterise the time-mean and time-varying components of the SAMOC in the South Atlantic Ocean and monitor the variability of the main Southern Ocean frontal systems associated with the Antarctic Circumpolar Current (ACC), south of Africa. Here we present processed magnitude and direction of hourly currents in the upper part of the water column (43.45 - 267.45m) from an ADCP located at a depth of 292m at Mooring 9 (34.50017°S; 17.1394°E) along the South Atlantic MOC Basin-scale Array (SAMBA) transect in the Cape Basin region of the South Atlantic Ocean, between 02 December 2015 and 09 April 2017.
Methods	A subsurface-mounted, upward-looking, 75 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was configured with a bin size of 16m and a blanking distance of 7m, and deployed at a depth of 292m at location M9 (34.50017°S; 17.1394°E), along the South Atlantic MOC Basin-scale Array (SAMBA) transect in the Cape Basin region of the South Atlantic Ocean. The instrument measured hourly magnitude and direction in the upper part of the water column (43.45 - 267.45m) between 02 December 2015 21h00 and 09 April 2017 12h00. These hourly values were corrected for magnetic declination, and only hourly values which showed ≥ 75% good beam data were used.
